> It recently came to my attention that we seem to have some bit rot in the heterogeneous data representation support such that if you configure with --enable-heterogeneous, even if you run on homogeneous machines, you can get segv's with tcp,sm,self.
>
> The heterogeneous support has never been enabled by default. AFAIK, only Cisco tests it regularly in its MTT. I'm be greatly surprised if many (any?) users use it at all.
>
> So I have to ask myself: why do we keep this functionality around? It seems like we should delete this code, simplify things a little, and move on.
